As I recall that's a very lightweight car. You could do some experimentation with disconnecting your power steering. I'll try and check this weekend if the belts are connected or are all separate. I'd really like to keep the power steering, and not opposed to getting rid of it. un-attaching the hoses would be a good test.

Being a manual opens up all manner of EOC opportunities. All the aero work you do will simply make your engine-off glides that much longer. The biggest bang for the buck is with a deeper air dam at the front and grille blocking. How much grille you block is up to you. Monitor your running temps so you don't go too far - some guys have been able to pretty much close off the entire rad. I just took my mud flaps off last night, and I plan on looking into doing some sort of air dam in the front and grille block, just not sure when yet.

Being a sedan, your aero at the back isn't great and difficult to change without limiting access to the trunk. You may want to spend most of your time making the rest of the car as slippery as possible before you get into a partial or full kammback that will work with your trunk lid.This is an idea I have been thinking about , but your right, The next things i'll probably do is the side mirror delete on the passenger, have to keep the driver side, and maybe the passenger side wiper. Radio isn't that great, so will do an antenae delete as well, and figure something else out for radio. With that long cummute Im going to need to figure out best way to spend my time as far as school goes. listen to recorded lectures etc.

Instrumentation is your friend, except it may not be your friend. A 91 Civic will have an OBD 1 port, and all the aftermarket instrumentation devices use OBDII, which has been the standard since '96 in the US. There are adapters available to convert an OBD1 port to use an OBDII scanner, but I don't know whether that will permit the instrumentation devices to talk to your system. If it does, I strongly recommend you go for it - more information makes you a better driver.I have looked into some instrumentation, I think I may start out with an auto-meter vacuum gauge and then look at a MPGuino

I'm seeing adapters on Amazon for $20 and less, and the OBDII-to-phone transmitter I got was about $25 or less. Torque Pro is about $5 and opens up a RAFT of instant readings, average readings etc. Again, I don't know how well Torque Pro, which is geared toward OBDII, will function with OBD1. As they say, your mileage may vary.
